The recent discussion about the value of Pi has been interesting and in some
cases heated. However, unless one is ready to throw away the Axioms of
Arithmetic, which unpins all mathematics, three things must be accepted:
1. Pi is transitional.
2. Pi is irrational.
3. Pi is the ratio of the circumference of a circle and to it's diameter.
These three irrefutable facts preclude any attempts to 'mandate', 'delcare'
or 'legislate' it's value.
People are free to use what ever approximation for it's true value that they
want provided condition three (above) is not violated within the available
means of measuring. For everyday purposes, the millimeter provides
sufficient precision for the need and satisfies this condition.
